Thanks. > When you use autoconf, the machine (and os) name will be set to "auto", hence m-auto.mak will always be used instead. FYI the whole m-xxx.mak, os-xxx.mak have been deprecated by autoconf. It'll only be used when ./configure-legacy is used (which I'm sure is broken by now). As an alternative to creating user.mak, you could also do: ./aconfigure LDFLAGS='-elf2flt' I have committed your patches in r1948 and r1949, thanks!
